and as illustrated in the accon'ipanying drawing, in which,-

F1 1 1s a vertical rear vlew of the devlce in readiness for use.

Fig. 2 is a central longitudinal sectional elevation as on line 22 in Fig. 1.

Fig. 3 is a top view of my device in operative position at an upper corner of a window.

Fig. 4; is a front view of Fig. 8 taken about as on line 11 in said Fig. 3.

Fig. 5 is an elevation of a preferred type of actuating lever used in the wedge device.

For the purpose of simplifying description of the device it will hereinafter be designated simply as window-wedge or expanding wedge and referring to the drawing by reference numerals, I have shown my device as applied in latching an upper corner of a window 10, guided between a parting strip 1.1,

a moulding 12 and the upright side window frame member 13.

The main object of this invention is to prevent rattling of a window, which fits loosely in the frame between the opposite members 13 and as a consequence of which there is an opening 14 between the vertical edge of the window and the adjacent member 13 (see Figs. 3 and 1).

The window wedge comprises three metal members which might most conveniently be termed the main or outer wedge, the secondary or inner wedge and the actuating lever 15, the device being shown in Figs. 1 and 2 as closed in readiness for use. The main wedge member comprises a single piece of flat spring-bar metall6 doubled as at 161) to form the thin edge of the wedge and above said closed part both arms of the member lie against each other for a predetermined dis- Serial No. 264,756.

tance, thence are spread apart gradually, one arm terminating and formed in a transverse bearing 16B for a transverse shaft 15A formed integrally with the lower end of lever 15, while the other arm extends above said bearing 16B and terminates preferably in an inverted U-shaped form 16C within the curvature of which is frictionally retained the transverse bearing part 1713 of the secondary wedge. Said'latter bearing, 17B comprises the upper end part of the secondary wedge which is of bar material similar to the main wedge, the bearing. part adapted to enga e an upper transverse shaft 15B of lever 15 parallel to shaft 15A both said shafts and the bearing members 1613 and 1713 being normally in a common vertical plane when the device is closed and the upper part of the lever extending of course vertically therefrom above the wedges. In the drawing the free end of lever 15 is illustrated a loop 15L forming a convenient finger-hold.

Below the bearing 17B of the secondary wedge it is closed under the shaft 15B and its two arms extend downwardly within the spread upper arms of the main wedge, one arm preferably terminating as at 17A further down within the main wedge, the lower end of the short arm being designated 176 (see Figs. 1, 2 and 4).

In the use of the wedge device it is inserted, while in closed condition as in Fig. 2, with its wedge end 16D downwardly into space 14 as far as possible without forcing it down, it being understood that the lever 15 is extending upwardly in .alinement with the wedge proper and being of course close to the face of the window frame member. Then the lever is swung down and inwardly over the adjacent window top as indicated by arrows 18 swinging the shafts 15A-15B to a horizontal plane, or even with shaft 15B below said plane, this action thus forcibly spreading the upper ends of the main wedge arms apart, causing the window 10, to be firmly engaged and pressing it horizontally to bear tightly against the opposite side window-guide means (not shown). The rear arm of wedge 16 is of course pressed against the frame member 13 and bearing 17 B is staant tionary. However, during this swinging of lever 15 it is obvious that bearing 17B is forced inwardly and down from its normal position vertically above bearing 16B and this of course moves the secondary Wedge 17 downwardly between the arms of the main Wedge 16 thus providing fur her forced Wedgingor spreading of the member 16 as the ends 17A and more downwardly (see Fig. Ordinarily one of these devices is sntficient to hold a slidable Window tight. It is obvious that the device being used on the upper corner of a Window the latter may be raised slightly from its loWestposit-ion to admit fresh air into a room. The amount of opening required at the bottom may be very small or insufficient for any burglar 0r prowler to force the Window up any further except by deliberate destruction of it.

I claim:

A11 expanding Wedge comprising a main Wedge member of iiat metal folded at approximately its center to form the point oi -the Wedge, one end of said inain Wedge comprising a transverse bearing, asecondary Wedge member Within the upper part of the main wedge and comprising a similar flatbar formed with a transverse bearing at its middle two 11118 normally flat against each other below said bearing, the other end of said main Wedge formed in inverted U-shape and opening toward its adjacent bearing but in spaced relation upwardly thereof and arranged to frietionally engage the bearing of the secondary Wedge, an elongated forked handle with two spaced transverse shafts fixed in the lower part of its fork, said bearingot' the inainwedge arranged'to engage he outermost of. said shafts of the handle said bearing of the secondary Wedge ar- "anged to engage the other shaft normally above the first hearing.

In testimony whereof I aflix my signature.
